通过8088查看Applications任务的logs时，会报以下错误，
Failed while trying to construct the redirect url to the log server.Log Server url may not be configured java.lang.Exception:Unknown container.Container either has not started or has already completed or doesn't belong to this node at all.
1，修改mapred-site.xml
<property> <name>mapreduce.jobhistory.address</name> <value>bigserver1:10020</value> </property> <property> <name>mapreduce.jobhistory.webapp.address</name> <value>bigserver1:19888</value> </property>
2，修改yarn-site.xml
<property> <name>yarn.log.server.url</name> <value>http://bigserver1:19888/jobhistory/logs</value> </property>
3，在bigserver1启动mr history
[root@bigserver1 hadoop]# cd /bigdata/hadoop/sbin/ [root@bigserver1 sbin]# ./mr-jobhistory-daemon.sh start historyserver
如果有日志：
container有日志
如果没有日志：
container没有日志
